18. Your stomach hurts.
Those stomach pains you have after too many cups of coffee shouldn’t be ignored. On its own, coffee’s high acid content can cause stomach pain and may increase the risk of stomach lining erosion and ulcers. Unfortunately, continued over-consumption can exacerbate these issues, even leading to bleeding in the digestive tract over time.
19. You’re losing weight.
While losing a few pounds may be on your to-do list, but if you’re losing weight unintentionally, you may want to consider cutting back on the coffee. In addition to making your stomach more sensitive, overconsumption of coffee can trigger a thiamine deficiency, a symptom of which just so happens to be nausea. Combined with coffee’s diuretic effect, you may shed a few pounds, but the process by which you’re doing so is anything but healthy.
20. You’re feeling weak.
All those trips to the bathroom that accompany your cups of coffee could be leading to some serious electrolyte imbalances over time. In addition to its magnesium-absorption-inhibiting effects, coffee’s diuretic effects can throw your electrolytes out of whack, potentially leading to weakness and fainting, as well as heart palpitations, nausea, fatigue, and vomiting.
